Validation of Patras Immunotherapy Score model for prediction and prognosis of patients with advanced NSCLC treated with nivolumab or pembrolizumab: results from a European multicentre study.

Background: Recently, the Patras Immunotherapy Score (PIOS) has been developed to estimate the survival benefit of patients with advanced non-small-cell lung cancer (aNSCLC) treated with nivolumab or pembrolizumab. The aim of this study was to validate the clinical value of PIOS in an external cohort of aNSCLC patients.

Methods: PIOS is a baseline formula produced by the combination of performance status, body mass index, age and line of treatment.

Can thromboprophylaxis build a link for cancer patients undergoing surgical and/or chemotherapy treatment? The MeTHOS cohort study.

Background: Patients with active cancer have a 4-sevenfold increased risk for venous thromboembolism (VTE) especially during systematic anticancer treatment. Simultaneously, surgery is an additional risk factor.

Methods: The Metaxas's Hospital THromboprophylaxis program in Oncological & Surgical Patients (MeTHOS) is a prospective, phase IV, observational, non-interventional cohort study, aiming to record the thromboprophylaxis practice patterns in high-risk active cancer patients undergoing surgical and/or chemotherapy treatment.

Case Report: Combination of Olaparib With Chemotherapy in a Patient With ATM-Deficient Colorectal Cancer.

Poly-ADP ribose polymerase (PARP) inhibitors are constantly increasing in their indications for use as anti-cancer treatment in various neoplasms, the majority of which are linked with BRCA deficiency. Preclinical data support the investigation of PARP inhibitors in other neoplasms exhibiting "BRCAness" or homologous recombination deficiency (HRD) as monotherapy as well as in combination with chemotherapy. With the current report we present the case of a heavily pretreated 55-year-old male patient diagnosed with stage IV ATM-deficient CRC, who was effectively treated with an off-label olaparib-irinotecan combination after exhaustion of all available treatment choices; furthermore, we discuss the existing data providing evidence for the use of PARP inhibitors in ATM-deficient CRC and encourage the implementation of next-generation sequencing (NGS) in patients with no other available treatment options.

High grade neuroendocrine carcinoma of the breast, first line and maintenance immunotherapy.

Small cell carcinomas (SCCs) are poorly differentiated neuroendocrine tumors that arise predominantly in the lung and gastrointestinal tract (GIT). Neuroendocrine carcinomas can occur in a variety of extrapulmonary sites throughout the body, including breast, larynx, GIT, prostate, urinary bladder, ovary and cervix. This is a case report of a 55-year-old Asian female patient with metastatic high-grade neuroendocrine carcinoma of unknown origin that responded notably to off-label nivolumab maintenance treatment after first-line carboplatin - etoposide chemotherapy and radiation.

Plerixafor-aided Mobilization of Peripheral Blood Hematopoietic Stem Cells to Support Subsequent High-dose Chemotherapy After a Prior Autologous Transplant.

Background: An appreciable proportion of patients in need of salvage high-dose chemotherapy (HDC) and autologous peripheral blood stem cell (PBSC) transplantation (PBSCT) fail to mobilize adequate numbers of hematopoietic progenitors, and plerixafor is applied for that purpose. Limited data exist on remobilization of PBSCs in patients who have relapsed after prior HDC + PBSCT. Herein, we report on consecutive patients that had undergone successful prior single or tandem HDC for a variety of malignant neoplasms in our institution, and later required re-mobilization of PBSCs in order to support further HDC cycles.

Primary Alveolar Rhabdomyosarcoma of the Breast in an Adult: An Extremely Rare Case.

Sarcomas of the breast constitute less than 1% of all malignant breast tumors and primary rhabdomyosarcoma (RMS) is a very rare entity with limited case reports in the literature. RMS is common in children and adolescents and rare in adults. Primary RMS arising from the breast is exceedingly rare in adults.

Myeloablative chemotherapy and autologous stem cell transplantation can lead to successful postengraftment mobilization of hematopoietic progenitors to support planned subsequent cycle(s) of high-dose chemotherapy and autografting in a patient with relapsed germ-cell tumor.

Salvage high-dose chemotherapy (HDC) together with autologous hematopoietic stem cell (HSC) transplantation (ASCT) represents a curative treatment option for patients with relapsed/refractory germ-cell tumor. Usually, 2-3 cycles of HDC are administered with encouraging results, and a sizeable percentage of patients experience long-term survival. However, an appreciable number of patients fail to mobilize adequate numbers of HSCs, adequate to support more than one HDC cycle.

Mapping the location of peritoneal metastases using the peritoneal cancer index and the correlation with overall survival: a retrospective study.

Purpose: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment for patients with peritoneal carcinomatosis (PC). Our objective was to identify new prognostic factors within the Peritoneal Cancer Index (PCI) score in PC patients.

Methods: 140 patients (60 ovarian, 45 colon, 14 gastric, 10 pseudomyxoma peritonei, 5 mesothelioma, 6 sarcoma) with PC treated with CRS+HIPEC from 2007 to December 2013 were retrospectively included.

Clinical history of patients with peritoneal carcinomatosis exluded from cytoreductive surgery & HIPEC.

Purpose: The aim of this study was to explore the natural course of peritoneal carcinomatosis (PC) in patients who are not fit to undergo cytoreductive (CRS) surgery and hyperthermic intraperitoneal chemotherapy (HIPEC).

Methods: Over an 8-year period (2006-2013) 320 patients were excluded from CRS and HIPEC at our center. Exclusion criteria were: (a) age >75 years; (b) ASA score ≥ 3; (c) extraperitoneal disease; (d) massive disease involvement of the small bowel; (e) disease involvement of the hepatic pedicle or the pancreas; (f) invasion of retroperitoneal space; (g) more than two stenoses of the small bowel.

Paclitaxel and carboplatin as neoadjuvant chemotherapy in patients with locally advanced breast cancer: A phase II Trial of the Hellenic Cooperative Oncology Group.

Purpose: This phase II study sought to evaluate the efficacy of the paclitaxel-carboplatin combination as neoadjuvant chemotherapy in patients with locally advanced breast cancer (LABC).

Patients And Methods: A total of 46 patients with LABC and inflammatory breast cancer (IBC) received 6 cycles of paclitaxel 175 mg/m2, followed by carboplatin, at an area under the curve of 6, before mastectomy. The primary endpoint constituted response to chemotherapy.

Mucinous but not clear cell histology is associated with inferior survival in patients with advanced stage ovarian carcinoma treated with platinum-paclitaxel chemotherapy.

Background: Mucinous and clear cell histology have been associated with adverse prognosis in ovarian carcinomas. The authors compared the outcome of these subtypes with that of serous tumors in patients who were treated with combination paclitaxel/platinum at their center.

Methods: Four hundred twenty patients with histologically confirmed, serous (n = 367), mucinous (n = 24), or clear cell (n = 29) ovarian carcinomas, International Federation of Gynecology and Obstetrics stage III or IV disease, and who were treated with paclitaxel/platinum after cytoreductive surgery were included in this analysis.

Efficacy of methotrexate/vinblastine/doxorubicin cisplatin combination in gemcitabine-pretreated patients with advanced urothelial cancer: a retrospective analysis.

Objective: Second-line treatment options in advanced urothelial cancer are limited. We investigated the efficacy of a methotrexate/vinblastine/doxorubicin/cisplatin (MVAC) combination after failure of gemcitabine/platinum chemotherapy.

Patients And Methods: Twenty-five patients with advanced urothelial cancer, who received second-line MVAC after first-line gemcitabine/cisplatin (n = 9) or gemcitabine/carboplatin (n = 16), were included in this retrospective analysis.

Pegfilgrastim administered on the same day with dose-dense adjuvant chemotherapy for breast cancer is associated with a higher incidence of febrile neutropenia as compared to conventional growth factor support: matched case-control study of the Hellenic Cooperative Oncology Group.

Objective: Recombinant human granulocyte-colony-stimulating factors such as filgrastim and pegfilgrastim have been employed as primary and secondary prophylaxis against neutropenia in cancer patients receiving chemotherapy. This study was conducted to evaluate the rate of febrile neutropenia in patients with high-risk early breast cancer receiving dose-dense chemotherapy and, as primary prophylaxis, either pegfilgrastim 6 mg fixed dose on the same day as chemotherapy or filgrastim on days 2-10 of each cycle. Secondary objectives included the rate of severe neutropenia, treatment delays and dose reductions.

Trastuzumab combined with pegylated liposomal doxorubicin in patients with metastatic breast cancer. phase II Study of the Hellenic Cooperative Oncology Group (HeCOG) with biomarker evaluation.

Objective: Combination of trastuzumab and anthracyclines in metastatic breast cancer (MBC) is precluded due to cardiotoxicity. Pegylated liposomal doxorubicin (PLD) is the least cardiotoxic among the anthracyclines. We performed a phase II study of trastuzumab and PLD with biomarker evaluation.

Paclitaxel- and platinum-based postoperative chemotherapy for primary fallopian tube carcinoma: a single institution experience.

Background: Primary fallopian tube carcinoma (PFTC) is a rare gynecologic malignancy with very few data existing on the activity of the combination of paclitaxel with a platinum analogue as adjuvant chemotherapy.

Methods: We retrospectively analyzed 41 consecutive patients with PFTC who were treated postoperatively with paclitaxel- and platinum-containing chemotherapy regimens.

Results: We observed 12 (63.

Two cases of complete response after imatinib mesylate treatment of advanced GIST.

Background: Imatinib mesylate has undoubted efficacy in the treatment of advanced gastrointestinal stromal tumors (GISTs), but complete responses have only been reported rarely.

Case Report: A 47-year-old man with liver metastasis from GIST achieved a complete response after 7 months of treatment with imatinib and a 47-year old woman with local relapse of GIST on the stomach after gastrectomy, showed complete remission, 9 months after treatment with imatinib.

Conclusion: Although the response rate is high in patients with advanced GIST treated with imatinib mesylate, complete responses remain rare.
